Fifth Wheel Instructions

Disconnect the light cord and air brake
lines. Use the dummy air couplings to keep
foreign material from entering the brake
lines.

Unlock the fifth wheel.

NOTE! If the operating rod is too difficult
to pull, back the tractor up slightly to re-
lieve any kingpin load against the fifth
wheel jaw.

Release the tractor park brakes and slowly
drive the tractor out from under the trailer.
Let the trailer slide down the fifth wheel
and pickup ramps.

After the trailer is uncoupled, the fifth
wheel will be in the open position. The op-
erating rod will drop and can be moved
around freely.
